Benzene

Hey guys!!!today im gonna talk about benzene.as you see in the picture below,benzene is a ring like structure.Melting point is 5.5 to 6.0degreee celcius(so srry bout the spelling).



 

 Its molecule is composed of 6 carbon atoms joined in a ring, with 1 hydrogen atom attached to each carbon atom. Because its molecules contain only carbon and hydrogen atoms, benzene is classed as a hydrocarbon.

Benzene is a natural constituent of crude oil, and is one of the most basic petrochemicals. Benzene is an aromatic hydrocarbon and the second annulene , a cyclic hydrocarbon with a continuous pi bond. It is sometimes abbreviated ph–H. Benzene is a colorless and inflammable liquid with a sweet smell. It is mainly used as a precursor to heavy chemicals, which are produced on a billion kilogram scale. Because it has a high octane number, it is an important component of gasoline, composing a few percent of its mass.Here's a pic of benzene bottle:
 Benzene is a natural constituent of crude oil, and is one of the most basic petrochemiscals. Benzene is an aromatic hydrocarbon and the second [n]-annulene ,a cyclic hydrocarbon with a continuous pi bond. It is sometimes abbreviated phenyl–H. Benzene is a colorless and inflammable liquid with a sweet smell. It is mainly used as a precursor to heavy chemicals, such as ethylbenzene and cumene, which are produced on a billion kilogram scale. Because it has a high octane number, it is an important component of gasoline, composing a few percent of its mass. Most non-industrial applications have been limited by benzene's carcinogenity.




The formulae for benzene is c6h6.Thanks guys for seeing this post.for now its goodbye!!!!!!

GLUCOSE

What is glucose?What is its formula?
Glucose is something which is very sweet and gives us instant energy.Its just like the process of photosynthesis.Glucose and sugar have a big difference.Glucose is hydrated and more sweeter than sugar.It gives us instant energy cause it contains extra water.An example of glucose could be anything which contains sugar.Example :Glucond -d

The formula for glucose is c6h12o6.

Indicators

Indicators are substances that show a change in colour when brought in contact with an acid or base.
Some Common indicators are Phenophthalein,Methyl Orange and Red/Blue Litmus Paper.
Below is a table which shows the colour change of these indicators

Indicators can also be prepared from plant.Such indicators are called Natural Indicators.
A Universal Indicator is a mixture of indicators chosen such that it shows a different colour for different PH values.It can also be soaked into a paper called PH paper.

Acidic,Basic and Neutral Substances

Acidic substances

Materials that contain an acid in them are called acidic substances.

Acids are of 2 types-

• Mineral Acid
• Organic Acid

Mineral Acid

A mineral acid is an acid derived from on or more inorganic compounds.They are not Organic.

Examples are-Sulphuric Acid,Nitric Acid.

Organic Acid

They occur naturally in animal and plant materials

Ex: Tartaric Acid from Grapes,Lactic acid from milk.

Characteristics of Acidic Substances are-

• They have a sour taste and are corrosive
• They are soluble in water

Acids can also be either dilute or concentrated.

Acids with more amount of water are called dilute acids.Acids with less amount of water are called concentrated acids.

Acids can also be either strong or weak.

Strong acids are highly corrosive and can cause burns.Ex:Nitric,Sulphuric Acid

Weak acids are not so destructive.

Basic Substances

Substances that contain a base are called basic substances.

Examples are Sodium Hydroxide,Calcium Hydroxide

Bases have many properties-

• They are bitter to taste
• Solutions of bases have a soapy touch
• They may or may not be soluble in water.

Bases that are soluble in water are called Alkalis.

Ex:Potassium Hydroxide,Sodium Hydroxide.

Bases can also be strong or weak

Strong bases are corrosive and can burn skin

Examples:Sodium Hydroxide

Examples of weak bases are Copper Hydroxide,Zinc Hydroxide

Neutral Substances

Some substances are neither Acidic nor Basic.These are called Neutral Substance.

When an acid reacts with a base,Neutralization reaction takes place and a Neutral Salt is formed.Here is an example of a neutralization reaction.

In this reaction Hydrochloric Acid reacts with Sodium Hydroxide to from Sodium Chloride(Common Salt) and Water.

Metals-In Brief

This is a brief note on metals and it will help you remember the important points.


A metal can be defined as an element or a compound that easily conducts both electricity and heat.

Some examples of Common metals are Iron(Ferrum),Copper(Cuprum),Nickel,Aluminium,etc.


Most metals are solid at room temperature.Mercury,a well known metal used in thermometers is liquid at room temperature.Most metals also have a high melting point.But Galium and Cesium are exceptions as they melt easily at about 86 F.

Metals have many properties which are

• Chemical Property
• Physical Property
• Mechanical Property And
• Electrical Property

Metals can be classified into the following groups

• Base metal-The chemical term Base metal is any metal that oxidizes or corrodes easily
• Noble Metals-Metals that are resistant to oxidization or corrosion.
• Ferrous metals-Metals that contain Iron as element,alloy or compound.
• Precious metals-Rare metals which have high value

ARGON [Ar]

Argon  /ˈɑrɡɒn/ ar-gon is a chemical element represented by the symbol Ar. Argon has atomic number 18 and is the third element in group 18 of theperiodic table (noble gases). Argon is the third most common gas in the Earth's atmosphere, at 0.93%, making it more common than carbon dioxide. Nearly all of this argon is radiogenic argon-40 derived from the decay of potassium-40 in the Earth's crust. In the universe, argon-36 is by far the most common argon isotope, being the preferred argon isotope produced by stellar nucleosynthesis in supernovas.Since argon is a noble gas,we cannot take a picture of it.However,I can only show you this:
 

BEST JOKES

What's the difference between Chemistry and cooking?

In Chemistry, you should never lick the spoon.

A group of organic molecules were having a party, when a group of robbers broke into the room and stole all of the guest's joules. A tall, strong man, armed with a machine gun came into the room and killed the robbers one by one. The guests were very grateful to this man, and they wanted to know who he was. He replied: My name is BOND, Covalent Bond.

The optimist sees the glass half full.
The pessimist sees the glass half empty.
The chemist see the glass completely full, half in the liquid state and half in the vapor state.

DDT

DDT is the common name for an insecticide.It's melting point is 108.5 degrees celsius and it is insoluble in water but it is very soluble in ethanol and acetone,colorless,odourless and it is especially useful for killing pests such as mosquitoes,flies etc:


It is also known as 'DICHLORO DIPHENYL TRICHLOROETHENE'.Here is a picture of a DDT bottle:

PHYSICS

Physics is a very important subject that is more important than chemistry.If you are a genius,you will be able to solve this:

                                                            E = Mc2

The full form of it is [energy = mass * velocity of light squared]
OH MY GOD!!!
Just think how fast it must be travelling.That means in one second it can travel more than 7 planets.I am really shocked.Let me know your thoughts in a comment.

What is chemistry?

Chemistry is another part of science like physics or biology.Chemistry is divided into:

• Organic chemistry
• Inorganic chemistry

Chemistry is a part of science whose central concerns are:

• The structure and behaviour of atoms (elements)
• The composition and properties of compounds
• The reactions between substances with their accompanying energy exchange
• The laws that unite these phenomena into a comprehensive system.

 Chemistry evolved from the medieval practice of alchemy. It's bases were laid by such men as Boyle, Lavoisier, Priestly, Berzelius, Avogadro, Dalton and Pasteur.

Chemistry is also the study of matter and energy and the interactions between them. This is also the definition for physics, by the way. Chemistry and physics are specializations of physical science. Chemistry tends to focus on the properties of substances and the interactions between different types of matter, particularly reactions that involve electrons. Physics tends to focus more on the nuclear part of the atom, as well as the subatomic realm. Really, they are two sides of the same coin.

Chemistry is also natural.It not only includes chemicals and elements but it also includes forest and all the other natural resources.

In some ways, physics might be considered more "fundamental" to the extent that it deals with matter and energy in a more general way, without the emphasis on particular substances. But the distincion can get pretty fuzzy; it is ultimately rather futile to confine any aspect of human endeavour to little boxes.

Chemistry is almost the central of all the sciences.Take a look at the picture below and you will understand everything:

I hope you guys understood and liked this post.Thank you for seeing this post.

INTRODUCTION

I am a very simple man who likes chemistry very much.I would be creating this blog for people who needs help on chemistry.This is the fun to learn process.Firstly people should learn the basics like what is chemistry?.This website is from classes 6-9 for those who need help.So please visit my blog to learn more about chemistry.Thank you for seeing this post.

This is a picture of mixing two chemicals.I think its copper sulphate.I would be posting more pictures and videos.WARNING RED ALERT: DO NOT TRY THIS AT HOME.If you guys try it this will happen to you:
